Discriminative coherence: Balancing performance and latency bounds in data-sharing multi-core real-time systems

Tasks in modern multi-core real-time systems share data and communicate among each other. Nonetheless, the majority of published research in real-time systems either assumes that tasks do not share data or prohibits data sharing by design. Only recently, some works investigated solutions to address this limitation and enable data sharing; however, we find these works to suffer from severe limitations. In particular, approaches that bypass …
